Thanks for the report, Jaap - I make the distance 477km. 

I do have some drift right at the start of my transmission, perhaps
10Hz, which is why I start each transmission with two dashes. After that
the drift is no more than 2-3Hz for the entire CQ lasting 5 minutes.

Yes, I do need to improve on that but even with an unstable carrier I
have managed 10 QRSs contacts, including the 73kHz two-way distance
record (lasting a year), the first G-ON QSO, 5 with DL, and HB9ASB.

I will build a better oscillator but in the meantime, unless I am
causing anyone QRM, I will continue using what I am sure you will agree
is a super technique for working DX.

Hope to work you some day. 73
